Katy Perry celebrated her 32nd birthday with a 1950s-themed party on Saturday night.

The Roar hitmaker - whose big day was on October 25 - sported a big blonde updo and a yellow pussy bow top for the bash, which featured Elvis Presley and Marilyn Monroe lookalikes and a giant game of Twister for guests including her boyfriend Orlando Bloom and friend Kate Hudson.

The star celebrated her 32nd birthday with an epic 1950s-inspired night on Saturday, complete with a giant game of Twister, Elvis Presley and Marilyn Monroe lookalikes and, of course, her beau Orlando Bloom and close pal Kate Hudson.

The sock hop bash, which was staged at Hudson High in honour of Katy's real surname Hudson, also featured a "detention" photobooth, and her guests shared some pictures from inside on social media.

Almost Famous star Kate shared a picture of herself, the birthday girl and other pals and wrote: "Happy birthday Hudson! #SockHop."

On another image she wrote: "Thanks @COVERGIRL for keeping everyone clean-cut and QT at Hudson High, Home of the Poodles. ... Principal Hudson. #KatyxCOVERGIRL (sic)"

Orlando wasn't with Katy on her actual birthday, but reportedly "buried" her in flowers to make up for the fact he was away shooting his next movie Smart Chase: Fire & Earth.

A source said: "Orlando buried Katy in flowers on her birthday and felt horrible he could not be there for her birthday.

"He has been super busy on set of his new movie in China and while things have cooled off a bit between the two, they still Facetime and text regularly. Katy still considers him her prince and she was blown away by the surprise flowers he sent from halfway around the world."
